Capriccio[edit]
While on the spectrum from Kodály's romantic style to the more aggressive style of Bartók, the Dialogo is considered closer to Kodály, the Capriccio is self-evidently Bartókian.
Because the second movement had the 'ambition' to become a sonata movement I wrote it in sonata form. It is a virtuoso piece in my later style that is closer to Bartók. I was 30 years old when I wrote it. I loved virtuosity and took the playing to the edge of virtuosity much like [Paganini].[14]
